for years and we're frustrated, too, that they're not out yet. >> i'm sure some of the people have had these injections would like these things more than anyone else. sanjay, these compounding pharmacies, it's not like they're mom and pop shops. i guess like they used to be. there are some 3,000 in the u.s. that are producing really large quantities of these custom drugs. i just find it amazing that the fda doesn't have any authority over them. what's their response to all this? >> well, you know, they'll say look, these are medications that are made by particular manufacturers and their rationale is as a compounding facility we're not actually manufacturing the medication and we may be dividing them up into different dosing, adding them to other things, for example, a medication that doesn't taste good, they may add flavoring, for example, so the child may take that medication. but you're absolutely right, a lot of pharmacies, maybe even ones by you, anderson, will compound their own medicine so if you go there and you want a slightly different medication, they may be able to create that for you.
